The mother of a 9-month-old boy found dead in a car seat inside his caretaker's closet is speaking out.

Authorities in Tarrant County, Texas, say the caretaker placed John Norris in a walk-in closet Monday to let him sleep.

When the caretaker later checked on the boy, he was dead.

An autopsy revealed the child accidentally suffocated.

A police statement issued Tuesday says the child was improperly secured in a child car carrier seat and strangled on a bottom belt strap while sleeping. The boy's neck was caught between a chest buckle and a strap mechanism.

In an emotional news conference Tuesday, Megan Norris spoke about losing her only child.
